Heart problems danger profile and administration methods throughout Forty five low-income along with middle-income nations around the world: A cross-sectional review of country wide consultant individual-level survey files.
Eighteen weeks after discharge, the infant is still on vitamin K supplementation. She did not have any further bleedings and no neurologic or developmental impairment.

Alpha-1-antitrypsin deficiency can lead to vitamin K deficiency in young infants even with adequate prophylaxis. Spontaneous haemorrhagic pericardial effusion was a new manifestation of vitamin K deficiency bleeding in our patient and should be considered and ruled out in young infants who present with acute anaemia and poor clinical condition.

Studies about the incidence and severity of coronavirus disease 2019 (COVID-19) in children are still significantly lower than those in adults. Moreover, data on the effect of COVID-19 in children with congenital heart disease (CHD) are limited. To the best of our knowledge, this study first reported mortality in a child with CHD who acquired COVID-19.

A 16-month-old boy presented to the emergency department due to shortness of breath, fever, cough, and poor oral intake. He tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). He required mechanical ventilation for rapidly progressing respiratory failure. The patient had a large mid-muscular ventricular septal defect (VSD) that was closed percutaneously at the age of 13 months. Moreover, we followed his hospital sequelae from admission to death.

This child had multiple risk factors, including malnutrition and persistent pulmonary hypertension (PH) after late closure of the VSD. The pre-existing PH could have been aggravated bcorroborate multisystem inflammatory syndrome in children, which was described recently among paediatric patients with COVID-19.
Malignant primary cardiac neoplasms are rare and primary cardiac angiosarcoma is the most common and aggressive subtype. It most commonly presents in middle-aged males and due to its non-specific clinical presentation, the diagnosis is often delayed until advanced disease is already present. Clinical presentation is determined by manifestations of local infiltration or metastatic disease and making an early diagnosis is extremely challenging.

A 15-year-old previously healthy boy was admitted to the emergency department with a history of pathological weight loss and functional decline. The patient was found to have a left-sided pneumothorax as well as bilateral diffusely spread pulmonary nodules on plain chest radiograph. Computed tomography chest confirmed widespread pulmonary metastases and a right atrial filling defect. Echocardiography revealed a right atrial tumour and transvenous endomyocardial biopsy of the tumour was done under fluoroscopic and echocardiographic guidance. A diagnosis of primary carthesia.
Transcatheter aortic valve implantation (TAVI) has become a first-line therapeutic option in patients with severe, symptomatic aortic stenosis at increased surgical risk. Despite its success, the TAVI procedure has been associated with acute life-threatening complications as myocardial infarction secondary to periprocedural coronary occlusion, annular rupture, or vascular injury.

A 79-year-old woman with a dysfunctional bioprosthetic valve following previous surgical valve replacement was hospitalized in our institution to perform a Valve-in-Valve Transcatheter Aortic Valve Replacement (ViV TAVR). Shortly after the implantation of an Evolut R valve (without complication), left ventricle dysfunction with apical akinesia and basal hyperkinesia was identified during bedside transthoracic echocardiography, in spite of a good prosthesis implantation and function. A concomitant Troponin elevation was noted, and the day-after resting electrocardiogram showed a lateral T-wave inversion. HADAchemical Coronary computed tomograppathological explanation can be formulated.
Management of heavily calcified coronary arteries is still a major challenge in interventional cardiology. Inadequate stent expansion in calcific lesions is the single most important predictor of stent thrombosis and in-stent restenosis. Rotational atherectomy (RA) is an important tool to modify the calcium burden but is associated with limitations and requires specific skills. Intravascular lithotripsy (IVL) is a novel technique to treat calcified stenotic lesions and has been proposed as an alternative to RA with promising results.

We report a case of a patient with severely calcified right coronary artery stenosis successfully treated with combination of RA and IVL.

In this case, we demonstrate that the RA and IVL are complementary strategies, not sufficient on their own and not alternative to each other.

Left ventricular outflow tract (LVOT) obstruction is an important determinant of the management of hypertrophic cardiomyopathy (HCM). With a nationwide shortage of amyl nitrite in 2019, we implemented a 'repetitive squat-to-stand' manoeuvre to provoke LVOT obstruction during echocardiography.

A 64-year-old female was referred with symptomatic HCM refractory to pharmacologic therapy. Transthoracic echocardiography showed minor LVOT obstruction with conventional imaging at rest and during Valsalva manoeuvre, but severe obstruction was confirmed with the repetitive squat-to-stand manoeuvre. Alcohol septal ablation via the first septal perforator was performed with subsequent resolution of symptoms.

Due to the dynamic nature of LVOT obstruction, a series of provocative manoeuvres including Valsalva manoeuvre, inhalation of amyl nitrite, and exercise are often necessary to maximally augment ventricular obstruction. The recent unavailability of amyl nitrite during a nationwide shortage prompted the implementang position decreases preload and afterload, both of which augment dynamic LVOT obstruction. Repetition of squatting and standing appears to enhance the sensitivity of the manoeuvre, particularly when exertional symptoms are reproduced. In this case, repetitive squat-to-stand manoeuvre led to the identification of severe LVOT obstruction which may not have been diagnosed otherwise, alteration of treatment to septal reduction therapy, and subsequent resolution of symptoms.
